To heat the motor oil and diesel fuel, connect an appropriate heating element as re-
quired.
CAUTION
Systems with jockey pump: Jockey pump starts immediately!
When the mains plug is inserted into the socket, the jockey pump starts. The jockey
pump fills the system with water and establishes the holding pressure.
Before plugging in the mains plug, read the notes on commissioning!

For correct operation and safety, the pump unit in question requires the installation of
other mandatory system components for compliance with the applicable directives and
standards.
Therefore, according to the Machinery Directive 2006/42/EC Annex II-1B, the commis-
sioning of the pump unit is PROHIBITED before the entire system in which it has been
installed has been completed and declared to be in conformity with the applicable dir-
ectives and standards.
For initial commissioning, we recommend that you contact your local Wilo service agent
or our service call centre. The commissioning of the pressure-boosting system must be
carried out by qualified personnel.
